Your explanations have clearly fallen flat. As has been show, they are based on unproven premises.
Do you believe that theft and murder are evil? Should they be illegal?
If we're using the legal definition of murder, it is evil. If we're talking about killing another human being, that is only evil in certain circumstances. Whether theft is evil is based on the circumstances of the theft. Robbing a bank to feed one's drug habit is evil. Stealing classified information from the Soviets in order to protect the US is not evil.
Why can't I murder someone if I want to?
Because murdering another human being violates that human being's right to live. Of course, we're relying on the legal definition of murder here.
What right to live? Is this just your opinion? Or is it based on something else? Many people don't see this "right," like federal judges who see a Constitutional right to stick scissors into a baby's skull. What right do you have to impose your value system on them?
If the Supreme Court decides to legalize infanticide, would you oppose their decision? Would it be an evil decision? Why/why not?
